Shuttle hook



Feb. 18, 1930. G. A. RUNKEL SHUTTLE HOOK Filed April 27, 1929Grantfl.fluml?eggmm Gamma Patented Feb. 18, 1930 UNITED STATES GRANT A.RUNKEL, OF LANCASTER, PENNSYLVANIA SHUTTLE HOOK Application filed April27, 1929'. Serial No. 358,580.

This invention aims to provide a tool for threading a shuttle, andparticularly a shuttle in which a mass of wool or the like is used toget the desired tension on the thread, the

construction being such that the thread may be pulled through the woolby means of the tool, without dragging any of the wool away into the poteye of the shuttle.

The invention aims to provide general improvements in a tool of the sortalluded to, and it will be understood that a mechanic who keeps withinthe scope of the claim can change the precise structure shown, withoutdeparting from the spirit of the invention.

Figure 1 is a longitudinal section of the shuttle into which the toolhas been thrust; Figures 2 and 8 are elevations showing the hook portionof the tool; Figure 4 is a cross section on the line H of Figure 2.

My tool can be used in various ways, but I will illustrate one specificapplication of it. The numeral 1, therefore, marks a shuttle carrying abobbin 2 on which the thread 3 is wound. The numeral 1 designates apartition carrying the pot eye 5, and behind the partition there is arecess 6 in which is mounted a mass of wool 7 or the like, held in acloth casing 8, the wool being used to keep the proper tension on thethread that extends through the wool and through the pot eye 5. A gooddeal of trouble has been met with in using threading tools in a shuttleof this kind, because the hook on the tool that pulls the thread throughthe wool 7 and through the pot eye 5, will also pull away some of thewool: an operation which is undesirable for reasons readily understoodby those skilled in the art.

The shuttle-threading tool forming the subject matter of thisapplication comprises a rod 9 preferably made of flexible metal, butstiff enough to keep any shape to which ithas been bent by theapplication of considerable force at the fingers of an operator. At oneend the rod 9 is provided with a handle 10. At its opposite end, the rod9 is supplied with a longitudinal slot 11 having a flared lateral mouth12 which opens through the side of the rod. The slot 11 and the mouth 12define a hook 14 having a bill 15 extended longitudinally of the rod andset back as at 16 from the prolonged outer surface 17 of the rod. Owingto the construction of the hook 14, and because the rod is smooth and'devoid of projections from the hook 1 1 to the handle 10, the rod maybe thrust through the pot eye 5, the thread 3 may be engaged with thehook 14, and the tool may be operated to pull back the hook through thewool 7 without catching and tearing the wool or dragging any of the woolinto the pot eye 5.

I claim:

A shuttle-threading tool comprising a rod provided at one end with ahandle, and supplied at the opposite end with a longitudinal slot havinga lateral mouth which opens through the side of the rod, the slot andthe mouth defining a hook having a bill extended longitudinally of therod and set back from the prolonged outer surface of the rod, the gridbeing smooth from the hook to the han- In testimony that I claim theforegoing as my own, I have hereto afiixed my signature.

GRANT A. RUNKEL.
